Calculate the tip and split the bill between any number of people. Choose a preset percentage or enter a custom tip. Instant results.
This tip calculator makes it easy to calculate the right tip and split a restaurant bill between any number of people. Select from common tip percentages (10%, 15%, 18%, 20%, 25%) or enter a custom amount. The round up feature rounds each person's share to the nearest dollar for easy cash payment. All calculations are instant and private — no data is ever sent to a server.
Tip calculation is straightforward arithmetic, but doing it quickly at the table — especially when splitting among multiple people — is where most people reach for a calculator. The math works like this:
Tip Amount = Bill × Tip Percentage
Total Bill = Bill + Tip Amount
Per Person = Total Bill ÷ Number of People
The round-up feature is particularly useful for cash situations. Rather than asking everyone to produce exact change, it rounds each person's share up to the nearest dollar. This means the server receives a slightly higher tip (typically a few extra cents per person), and no one needs to dig for coins. The calculator clearly shows both the exact per-person amount and the rounded-up version so your group can decide which to use.
A group of 4 friends goes out for dinner. Their bill comes to $92.00 before tip. The service was excellent, so they want to leave a 20% tip.
Tip amount: $92.00 × 0.20 = $18.40. Total bill: $92.00 + $18.40 = $110.40. Per person: $110.40 ÷ 4 = $27.60 each. With the round-up feature enabled, each person pays $28.00, bringing the total collected to $112.00 — giving the server a $20.00 tip instead of $18.40, a small boost that is easy to manage with cash.
If one person is paying by card and wants to cover the full amount, they enter $112.00 on their card and each of the other three hands them $28 cash. The calculator makes these splits clear so there is no awkward math at the table and no one accidentally undertips.
The standard restaurant tip in the US is 15–20% for good service, with 20% being the most common benchmark today. For truly exceptional service, 25% or more is appreciated. For counter service or fast casual where you order at the register, tipping is optional but 10–15% is common. For buffets, 10% is typical since servers do less work. For food delivery, 15–20% of the order total is standard, though tipping more for long-distance orders or bad weather is a common courtesy.
The fastest way to calculate 20% mentally is to move the decimal one place left (giving you 10%), then double that result. For a $46.00 bill: 10% = $4.60, doubled = $9.20 tip, total = $55.20. Alternatively, multiply the bill by 0.20. For 15%, take 10% and add half: 10% of $46.00 = $4.60, half of that = $2.30, sum = $6.90 tip. Our tip calculator handles any percentage instantly, including custom percentages, so you never need to do the mental math at the table.
To split a bill evenly: add the tip to the total, then divide by the number of people. For example, a $92.00 dinner for 4 people with a 20% tip: tip = $18.40, total = $110.40, per person = $27.60. For cash situations, you may want to round up to the nearest dollar ($28/person) so the server gets a slightly better tip. Our calculator handles any group size and includes a round-up option for easy cash payments. If people ordered very different amounts, consider splitting by item using a restaurant bill splitting app.
Most etiquette guides recommend tipping on the pre-tax bill amount, since the sales tax goes to the government rather than the server. However, tipping on the post-tax total is also widely practiced and always appreciated. On a typical $60 meal in a state with 8% sales tax, the difference between tipping on pre-tax ($60) versus post-tax ($64.80) at 20% is about $0.96 — less than a dollar. Since the practical impact is so small, the most important factor is simply tipping a fair amount for the quality of service, regardless of which base amount you use.
In 2026, 20% has become the widely expected standard tip at full-service restaurants in the US, reflecting years of gradual upward drift from the old 15% norm. Many restaurant payment terminals now default to 18%, 20%, and 22% as their preset options, nudging customers toward higher amounts. For large parties of 6 or more, most restaurants now add an automatic gratuity of 18–20% — always check your bill before adding an additional tip on top. For exceptional service or if you are a regular at a neighborhood spot, 25% or more is a generous way to show appreciation.
